Last time I checked, the "lan" alias should do, i.e. lan0, lan1, …, but
not the "eth" one.[1]

However I leave rename to systemd.
lspci
01:09.0 Ethernet controller:
ifconfig
enp1s9:
dmesg
systemd-udevd: renamed network interface eth0 to enp1s9

If you contemplate it from the perspective of the NetworkManager/nmcli
you'll understand. ;)
